Question

A chemistry experiment is being conducted in a beaker. The reaction involves nitric acid and tin metal. Your teacher tells you to cover the beaker to prevent any spattering of the material during the reaction. Which piece of equipment would be best suited to cover your beaker?

Answer 1

A watch glass is ideally suited to cover a beaker during a chemistry experiment to prevent spattering while still allowing gases to escape.

Step-by-step explanation:

To cover a beaker during a reaction between nitric acid and tin metal to prevent spattering, a watch glass is typically used. A watch glass is a circular, slightly concave piece of glass that fits on top of a beaker. It allows gases to escape while preventing any splashing out of the beaker. In a laboratory setting, following appropriate safety procedures is critical, including the use of the correct equipment to ensure that reactions are contained and personnel are protected.
